Clean up the wmake control directory Make and remove the include
directories generated for libraries.

The targets correspond to a subset of the 'wmake' special targets:
    all       all subdirectories
    exe       cleans dir/Make
    lib       cleans dir/Make and dir/lnInclude
    libso     cleans dir/Make and dir/lnInclude
    libo      cleans dir/Make and dir/lnInclude
